COMBINED GRAIN RECLEANER AND GRAD ER.

Application filed. April 24, 1926, Serial No. 104,345, and Canada March 9, 1925.

The invention relates to improvements in combined grain recleaners and graders and an object of the invention is to provide a ma chine which will effectively clean the various grains and which can be utilized to grade the cleaned grain.

A more particular object of the invention is to provide a specially constructed discharge spout for receiving the initially cleaned grain from a reciprocated shoe or such like, the discharge spout being associated with a blower fan and being adjustable in position and also adjustable in size and being provided with an adjustable gate to vary the size of the dischargeopening.

A further object of the invention is to provide a fan construction which will effectively distribute the blast within the spout.

With the above more important objects in view, the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described, reference being bad to the accompanying drawings, in which r I Fig. 1 is a side view of the machine.

In the drawings like characters ofreference indicatecorresponding parts in the several figures. I v j The frame of the machine is of the customary type presenting the usual corner legs 1 connected byupper, lower and intermediate side bars 2, 3 and 4 and by front and rear cross bars 5 and 6. Brace bars and 8 are also providedto reinforce the sides of the machine.

The upper part'of the frame supports a ho per 9 which is provided witha'n adjustab' .e ate 10 controlling the discharge through the fted outlet 3.1,. {Snyderlying the hopper 3;

locate an inclined reciprocated shoe 12 which is constructed as now described. It presents a troughshaped body embodying aibottom 13 and opposing side walls 14. Within the body I mount an upper screen 15 and an under screen 16 and beneath the screen 16 and slidmg on the bottom I locate scraper 17 which is adapted to keep the underside of the screen 16 clean. The riddle is formed from a number of suitably spaced crossbars 18 (see Figparallel tie bars 19.

The forward end of the screen 15 discharges onto a plate 20 and the plate directs the grain to a laterally discharging chute 21. The screen 16 discharges grain onto a cross plate ure 7) connected by lengthwise extending shoe and has the rearmost end thereof curved downwardly. A laterally discharging chute 23 is arranged to receive the grain discharging over the rear end of the bottom plate/13. Theshoe is supported for vibratory movement by front and'rear pairs of hangers 24: having their lower ends pivotally attached to the sides 14 and their upper ends pivotally '22'which extends beyond the rear end of the swung from the upper sidebars of the main frame.

The main driving shaft 25 of the machine is rotatably mounted in suitable bearings carried by the intermediate bars 4 and in a location adjacent the forward end of the shoe. A fan shaft 26 is rotatablymounted in suitable bearings 26' carried by the lower bars 3 and is located underneath the rear end of the shoe. A fan 27 is secured to the shaft 26 and is formed in the manner-best shown in Figure 8 Where it will be observed that the cylindrical fan casing 32,;the fan casing hav-' ing openings 33 in the ends thereof topermit exterior air'to enter the casing. The casingis rotatablymounted on the shaft 26 and to this end I securehorizontally disposed bars 34 to the ends of the casing, these bars being fitted with upstanding bearings 35 rotatably receiving the shaft 26 (seeFigurelO Gates 36 are pivotally'attached to the en act the my it can control the amount of air admitted through the openings 33. The gates are supported by swinging bars 37 which operate over toothed racks 38 secured to the casing sides, the teeth of the racks holding the bars 37 in any adjusted position.

A discharge spout indicated generally by the reference numeral 39 is attached permanently to the fan casing, the upper end of the spout being substantially vertical whilst the lower end thereof curves inwardly and downwardlyand meets the lower part of the casing tangentially. The spout is formed from two main parts, a non-adjustable body portion 40 and an adjustable rear portion 41., the body portion comprising an inner plate 42 having the lower end curving inwardly and secured to the fan casing and the upper end curving rearwardly and forming a hood 43.

To the latter plate I secure opposing wooden side boards 44 and to the inner faces of these side boards I fasten metallic plates 45 which have their lower ends curving inwardly and downwardly and communicating with the sides of the fan casing. Between these side plates the adjustable rear portion 41 of, the spout is located, such rear portion being of a trough-shape and presenting opposing vertically extending side wings 46. The side wings are fitted with parallel inclined slots 47 which receive pins 48 carried by the side plates 45 with the result that the portion 41 of the spout can be moved towards and away from the front portion 40 to increase or diminishthe cross sectional area of the spout as desired.

To the lower. ends of the wings 46 I secure spaced pairs of batons 49 and 50 and these slidably receive a downwardly and inwardly inclining deflector plate or chute 51 formed continuous with the body plate 41 and inclining in the same direction as the slots 47. An extension plate 52 passes tangentially from the lower side of the fan casing and has the ends thereof connected to the side plates 45 and the rear end of the plate 52 overlies the plate 51 to provide a discharge passage for grain. To the upper end of the plate 41 I secure a cross board 54 and this cross board carries a hinged gate 55 at its upper edge. An upstanding divisional board 56 is secured centrally tothe extension plate 52 to divide the blast emanating from the tan.

From the above it, will be apparent that when the fan is rotated in the direction indicated by the applied arrowvFigure 3, there will be a blast outwardly and upwardly through the spout and that I can vary the velocity of the blast within the vertical portion of the spent by increasing or. diminishing the cross sectional area of the spout through the adjustment of the rear portion 41 thereof.

Means is provided for adjusting the rear portion of the spout, such embodyin an upper pair of levers 57 attached pivotally at 58 to the portion 40 of the spout and pivotally connected at 59 to the portion41 thereof and a pair of hell cranks 6O similarly connected to the spout parts, one of the arms of each bell crank being arranged to ride over a toothed quadrant (31 attached to the non-adjustable side of the spout. Obviously by swinging the bell cranks up or down, I widen or diminish the width of the spout.

The inner side of the spout carries a feed trough 62, the upper end of which underlies the plate 22, the arrangement being such that grain dischar ing from the plate onto the trough 62 will be delivered to the interior of the spout and will fall within the spout in a stream extending completely across the spout so that the upgoing blast from the fan passes therethrough.

A stationary ho )per 63 is located beneath the fan casing and is adapted to receive the grain discharging from the lower end of the chute 51. A conveyor trough (34 communicates with the hopper and extends forwardly and upwardly being suitably supported by a cross bar extending between the front legs. The troi'lgh supports rotatably, upper and lower conveyor shafts 66 and 67 provided with rollers 68 and the rollers carry an endless belt which is fitted with suitably spaced slats 69 adapted in the rotation of the belt to gather the grain in the hopper '63 and sweep it upwardly over the bottom of the trough and discharge it at the front end of the machine.

The shaft 25 is fitted with similar eccen tries 70 receiving straps 71 located at the front ends of pitmans 72, the rear ends of which are connected pivotally at 73 to the sides of the shoe 12. The brace bars 8 support a cross rod 74 which carries a pair of hooks 75, the hooks being cau ht in holes 7 6 located in the forward ends of the bars 19.

The shaft 25 is supplied at the op )OSltQ ends with pulleys 77 and 7 8 and centra ly of its length with a chain wheel 79. The pulley 77 is used as the driving pulley and that 78 is connected by a cross belt 80 to a pulley 81 secured to the fan shaft. The chain wheel 7 9 is connected by a chain 82 to a chain wheel 83 secured to the shaft 66.

According to the above arrangement when the pulley 77 is rotated in the direction indicated by the applied arrow Figure 1, the fan and conveyor are driven in the directions indicated by the applied arrows in Figure 4 and the shoe is reciprocated.

Owing to the riddle or scraper being held stationary whilst the shoe is reciprocated, the riddle serves effectively to clean the under side of the screen 16.

The upper end of the spout is adjustably supported from the main frame by utilizing adjusting bolts 84 attached to the side boards 44 of the spout and operating in slots 85 formed in bars 86 attached to the frame, the slots being more or less radial to the shaft 26.

grain discharging from the shoe.

When this machineis to be used for clean ing the heavier grains such as wheat, rye and peas, the spout is brought to its most vertical position and the rear portion 41 thereof is closed in to give the smallest cross sectional area to the spout. This increases the force of the up going air blast within the spout and also gives a somewhat shorter travel for the grain falling down in the lower part of the spout from the trough 62. The dust, chaff and lighter seeds are blown out the upper end of the spout in the blast and the heavier grain is discharged through the opening 53 to the hopper 63 from which it is elevated by the conveyor.

When one is recleaning somewhat lighter grains such as barley and eats, the spout is adjusted by means of the bolts 8% to give it a somewhat inclined posit-ion and the rear portion 4.1 thereof is also moved back to increase the cross sectional area of the spout. This decreases the velocity of the blast and gives a somewhat longer travel to the grain falling across the spout from the trough.

l/Vhen light grains such as brome and rye grass seed are being recleaned, the spout is given a considerable inclination and the adjustable part of it is well opened up to give a large cross sectional area. Such results in a decrease in the blast and a longer travel of the falling grain.

Whilst I have entered into a detailed description of the manner in which the spout is formed so that it can be adjusted to vary the cross sectional and have also given a detailed description of the manner in which it is held in its various inclined positions, it will. be readily understood that such structures could be easily modified without departing from the spirit of the invention.

I might point out also that the shoe operates to initially clean the grain and that the spent and fan blast are utilized to reclean the Obviously the arrangement of the shoe for initially cleaning the grain could be modified as the novel features of the invention reside more particularly in the spent and fan rather than in the particular type of shoe used for initially cleaning the grain prior to its delivery to the spout. I

I have'found that by providing the divisional plates 31 and the board 56 I effectively distribute the air blast in the spout.

What I claim as my invention is I 1. In a grain recleaning device, a pivotally mounted fan casing, a driven rotatably mounted air blast fan within the casing, an upwardly extending spout having the lower end continuous with the casing and the upper end thereof adjustably supported thereby permitting of the spout taking-various in clined positions, means for feeding the grain to be cleaned into thespout to fall in a distributed stream across the up going air blast within the spout, means for discharging the.

cleaned grain from the lower end of the spent and means whereby the spout can be adjusted to increase or diminish the cross sectional area thereof and to increaseor diminish the travel of the falling stream of grain there across.

2. In a grain recleaning device, a rotatably mounted fan easing, a driven air blast fan rotatable withinthe casing, an upwardly extending inclining spout having the lower end thereof carried by and communicating with the interior of thefan casing, said spout hav' ing front and rear walls, sectional side walls connecting the front and rear walls and adjustable to vary the distance between said front and rear walls to thereby vary the cross sectional area of the spout, a feed trough opening through the front wall of the spout and adapted to feed the grain to be cleaned in a falling stream across the lower end of the spout, the arrangementbeing such that adjustment of the spout to vary the cross sectional area thereof results in a lengthening or shortening of the path of the falling stream of grain through the spent and a discharge chute located at the lower endof the spout and at the under side and beneath the falling stream of grain.
